スの如き民生用の安価なトランスに使用するには
不向きな点があつた。(Prior Art) Conventionally, various types of coil insulating bands for obtaining a coil margin have been provided, such as those in which continuous convex portions are integrally molded on both side edges of an insulating sheet made of plastic or the like. However, many of these have disadvantages in that they are not suitable for use in inexpensive transformers for consumer use such as switching transformers, such as poor workability or high costs due to the large number of machining steps.

（考案の構成）
以下、図に沿つて本考案を説明する。第１図は
本考案の第１実施例を示しており、図において１

からなる凸部２がほぼ等間隔で多数付着されてい
る。(Structure of the invention) The invention will be explained below with reference to the drawings. FIG. 1 shows a first embodiment of the present invention.
3 shows a band-shaped insulating sheet having a width approximately equal to the winding portion B1 of the coil bobbin B. This insulating sheet 1 is formed by cutting, for example, a thin plastic sheet or paper into a band-like shape. Winding part
It has sufficient flexibility so that it can be wrapped around B 1 . A large number of protrusions 2 made of a quick-drying nylon adhesive such as polyamide are attached to both side edges of the surface of the insulating sheet 1 at approximately equal intervals.
第２図は本考案の第２実施例を示すもので、こ
の実施例は第１実施例と同様に速乾性接着剤から
なる凸部２′を、絶縁シート１の表面両側縁に連
続的に形成して付着せしめたものである。 FIG. 2 shows a second embodiment of the present invention. In this embodiment, like the first embodiment, convex portions 2' made of quick-drying adhesive are continuously formed on both sides of the surface of the insulating sheet 1. It is formed and attached.
これら第１および第２実施例において、凸部
２，２′を形成する方法としては、例えば一定の
速度で送られる絶縁シート１の表面両側縁の上方
から、速乾性接着剤を間歇的（第１実施例）また
は連続的（第２実施例）に滴下することにより、
その接着力および速乾性を利用して極めて容易に
凸部２，２′を付着せしめることができるもので
ある。なお、速乾性接着剤の付着量を調節するこ
とで、コイルの巻数に応じた凸部２，２′の高さ
を任意に得ることができる。 In these first and second embodiments, the method of forming the convex portions 2, 2' is, for example, by applying a quick-drying adhesive intermittently (intermittently) from above both edges of the surface of the insulating sheet 1, which is fed at a constant speed. By dripping (Example 1) or continuously (Example 2),
Utilizing its adhesive strength and quick-drying properties, the protrusions 2, 2' can be attached very easily. By adjusting the amount of quick-drying adhesive applied, the height of the convex portions 2, 2' can be arbitrarily determined according to the number of turns of the coil.
これを使用するには、第３図に示す如く、コイ
ルボビンＢの巻部B1の表面に本考案にかかるコ
イル用絶縁帯を巻装し、その凸部２，２′の相互
間に位置するように下巻線C1を施すと共に、こ
れらの下巻線C1の上に再びコイル用絶縁帯を巻
装して凸部２，２′の相互間に上巻線C2を施す。 To use this, as shown in Fig. 3, the insulating band for the coil according to the present invention is wound around the surface of the winding part B1 of the coil bobbin B, and the insulating band for the coil according to the present invention is placed between the convex parts 2 and 2'. At the same time, the lower winding C 1 is applied as shown in FIG. 2, and the insulating band for the coil is again wound on these lower windings C 1 , and the upper winding C 2 is applied between the convex portions 2 and 2'.
この際、第１実施例によれば、縦に並んだ凸部
２の相互間から下巻線C1または上巻線C2の引出
し線を引出すことができるため極めて便利であ
り、また、第２実施例によれば速乾性接着剤から
なる凸部２′自体がある程度の伸縮性を有するた
め、コイル用絶縁帯を巻部B1に巻付けた際に凸
部２′が巻部B1の外周面によく馴染み、凸部２′
が破断する等の不都合が全くない。 At this time, according to the first embodiment, the lead wire of the lower winding C 1 or the upper winding C 2 can be drawn out from between the vertically arranged convex portions 2, which is extremely convenient. According to the example, since the convex part 2' itself made of quick-drying adhesive has a certain degree of elasticity, when the insulating band for the coil is wound around the winding part B1 , the convex part 2' becomes the outer periphery of the winding part B1. Familiar with the surface, convex part 2'
There are no inconveniences such as breakage.
